STM32 MCUs Products

Because I tried to make the MCU sleep mode. I therefore tried to configure the sys causing errors. I want to start again I tried erase the ship but it wasn't successful. I want to configure the MCU to be the factory default. What are the steps to do?

Muxed PSRAM compatible memory

Hello,I am using a STM32H745 in LQFP144 package and as far as I understand it supports only muxed PSRAM since the pins for non-muxed memory are missing in this package and the CubeMX software does not have the option to setup non-muxed PSRAM on this...

STM32 standby wake-up BUG?

STM32 standby mode, standby wake-up pin PA0 and RTC wake up, both can work normally. The problem encountered is: If the wake-up pin PA0 is kept high, when the PA0 high-level hold time exceeds the wake-up time set by the RTC after standby, the chip di...

Integraten Operation amplifier in STM32F3030

In datasheet is 6.3.22 Operational amplifier characteristicsILOAD Drive current max 500uA.Does this mean the amplifier cannot control the negative current?RLOAD Resistive load min 4kOhn? Why 4kjOhgm, for exmple curtent to 4kOhm for 2.5V is 625uA, thi...

STM32H7 Timer Output Compare mode (OC mode)

hi sir, I want to use timer channels to OC mode. In that same timer interval i need set time to channel 1 come 1 time and channel 2 comes 5 times.example: In 1 milli second timer i need set & reset channel 1 for time and every 200 micro second set ...

How can I read data from BMP 280 bosch sensor with STM32F0 Discovery kit via I2C.

I am trying to read data from from BMP 280 bosch sensor but could not able to do , Any expertise on I2C/ Bosch sensor please?I could able to communicate with my sensor by checking if the device address is right or wrong using function : HAL_I2C_IsDev...

I'm trying to port some firmware from nucleo-F334 to nucleo-G474 for the HRTIM timers and the CubeMX for G474 for HRTIM1 is not working. I found some missing statement in the initialization.

I found that the CubeMX 5.3 initlization code missing a part; specifically the HRTIM clock initialization where the PLL is defined. There's a related constant that also needs to be defined. In any case can someone confirm the problem and how long it ...
